Abstract :
LaB6 cathode is the emitter of choice in electron beam lithography tools. In commercial LaB6 cathodes, the (100) crystalline plane is used as the emissive surface. Values of (100) and surrounding crystalline planes workfunction (WF) vary widely in literature. We have devised and implemented a simple, robust technique for evaluating LaB6 cathode workfunction.
